Q&A of LED Curing Light Unit (1/2)
Something important of LED curing light unit to help our customers know it better.
Recently we received many inquiry and orders from our customers, here we sum up the Q&A of the LED curing light unit to help our customers understand it better as below.
About light curing time
Q: How long is the appropriate time for light-curing fillings to be illuminated? How long is the best time to light-cure a bonding material? What is the light time of the dual-curing material used for bonding restorations?
A: Different materials have different initiation systems and require different excitation wavelengths and light exposure times, so you need to follow the operating instructions provided by the manufacturer to select the appropriate wavelength, the required light intensity and the required exposure time.
Q: Are there any disadvantages to too much irradiation time?
A: The effect on the light-curing material itself is minimal, but excessive heat production can irritate the pulp and soft tissues.
Q: Bonding inlays light time should be extended?
A: Bonding inlays generally require the use of dual-curing resin Clementine, light curing combined with chemical curing, this dual-curing material is recommended for light curing first, there are literature reports, the initial polymerization occurs under the light curing trigger, the strength of the material will improve, better edge line sealing, better staining resistance, light curing time please follow the instructions of the material.
About Light Intensity
Q: How often is the intensity generally tested?
A: 3M light curing light intensity decay very little, but we still recommend testing the light intensity before use every day to ensure the accuracy of the output light intensity. At the same time 3M light curing lamp charging base are equipped with a light intensity meter, the determination of light intensity is very convenient.
Q: Light guide head put disposable plastic sleeve will affect the intensity?
A: This disposable plastic cover will lead to a certain degree of light intensity attenuation, especially the plastic cover with an interface, to avoid the interface obscuring the front of the light guide head; literature reports, cling film caused the least attenuation; we also recommend that before and after the plastic cover to measure the light intensity comparison, to confirm that the light intensity still meets the light requirements before.
Q: Is there a big difference between the common light guide rod black and transparent color compared to the light guide efficiency?
A: The black light guide bar can eliminate astigmatism, prevent glare and improve beam collimation while protecting the eyes of patients and doctors.
Q: How do I measure the light intensity, the easy way?
A: 3M light curing lamp charging base can test the light intensity, simple and convenient.
Q: Light curing lamp used for a long time, the light intensity decayed what to do?
A: Regular measurement of light intensity, if the attenuation is too much, you need to replace the new light curing lamp, so as not to affect the effect of light curing.
Q: the old halogen lamp, how effective?
A: The old halogen lamp light intensity decay quickly, you need to test the light intensity frequently, it is best to confirm the light intensity before use every day.
